Fair point. I concede that Charlie never said that, but I stand by what I said on the general issue because many Christian pastors do make obedience to some point of Mosaic law a requirement for salvation while at the same time saying we are saved by grace. Otherwise they require obedience to some point of the law to obtain the blessing that comes of obedience to the commandment they selected and separated out of the law, saying that believers will be cursed if they don't comply. But you can't obey part of the law without obeying all of it, and Paul makes it clear that a human can't be saved by the law. The Jews of his day wanted him to include just one Mosaic commandment in the Gospel to make it acceptable, just one, but he wouldn't budge an Inch because he knew where it would lead.

How can they say we can be cursed by not obeying the law when Jesus nailed the law to his Cross. His blood doesn't just cover our sin, it eradicates it in an exchange in which we receive a gift of righteousness through our faith. We don't need an external law because the law is written on our hearts according to Jeremiah 30:33. In this passage God said he was going to make a new covenant that wouldn't be like the one he made with the fathers who died in the wilderness after they left Egypt. He said it wouldn't be "according to" that previous covenant and that means it wouldn't operate on the same principles. We have to get this right. The new covenant, everything in the new covenant, is accessed by faith, it is grace that teaches us to walk righteously, and the love of God is our pattern for righteous living.

I have no problem with people observing days if their conscience tells them they must, but I do have a problem with people telling other people they must, and I have a problem with people offering a free gospel of grace and then slapping on the chains of the law as soon as the church door closes behind them.
